How Do You Measure O-ring groove size?

How to Measure O-Rings

Place the O-ring on a clean, flat, level surface.
Determine the inside diameter by using a ruler to measure from one inner edge to another.
Use a ruler to measure the diameter, from one outer corner of the O-ring to the other outer corner.
Finally, measure the cross-section.

How should an O-ring fit?

To provide an effective seal, the O-ring’s inside diameter (I.D.) must be smaller than the piston groove diameter, so that the O-ring is slightly stretched, fitting snugly in the groove. This stretch should be between 1%-5% with 2% as the ideal in most applications. A stretch greater than 5% is not recommended.

How are O rings calculated?

To measure the outside diameter, use a ruler to measure from one outer edge to the other of the o-ring. You can determine the third diameter of the O-ring with 2 diameters using the following equation: Outside Diameter (OD) = Inside Diameter + (2 x Cross Section). Inside Diameter (ID) = OD – (2 x Cross Section).
